Abstract

Illumination arrangement (2), profiled bodies (5) of a light permeable material being formed in a base body (4), which profiled bodies are spaced apart from one another by means of recesses (6). To each profiled body there is applied a luminous means (7) which emits light into the corresponding profiled body. The light is directed internally by the profiled body (5) to an emission surface of the base body (4) in such a manner that it emerges there within a maximum emission angle range, to avoid dazzling an observer. As luminous means (7) a flat fluorescent lamp can in particular be employed.
